Windows 7: Your best NAS solution for SOHO? [small offc, home offc]

gang
I'm needing to get caught-up on the best low/moderate-cost NAS etc solutions for storage of the ever-expanding pile of data, for those who for whatever reason don't trust 'cloud'.



in surveying the hardware/sftw/frmwr integrated turnkey 'boxes' - all of them have their shortcomings, as you know, and none are full "gold star" anvil-like solid.
as I read of the various issues, I gotta wonder, given the rapidly imploding desktop PC market if I wouldn't do better by just building up my own redundant unit with windows and a minitower?

since I do tech work for soho, I need to land upon a "standard" way of getting the job done. right now I don't see anything I'm enthusiastic about, or confident in. I like Paragon Backup & Restore software [though its interface is too cryptic for most ordinary folks] or 'Backup NOW' [the reverse... very easy], but I'm ambivalent about the linux-derivative "turnkey" enclosures & such.

what do you do? pro/con?
I bet there is a fairly busy thread around here somewhere re: this...

EDIT: MODS, my bad... I should have been in the Backup/Restore folder. I'll piggyback one of those.
